<h3>About Engineered Marine Products (EMP)</h3><p><strong>Engineered Marine Products</strong>, widely known in the boating world as <strong>EMP</strong>, has been a trusted name in marine parts manufacturing for over 40 years. The company supplies OEMs, distributors, dealers, and rebuilders worldwide with high-quality aftermarket components engineered to meet or exceed original equipment manufacturer (OEM) specifications. Whether you maintain a weekend fishing boat or a performance inboard, EMP&apos;s extensive catalog is built to keep marine engines running reliably season after season.</p><h3>A Marine Parts Specialist Built on Engineering Precision</h3><p>EMP&apos;s foundation is precision manufacturing. Their design and production processes leverage modern engineering technology, with a focus on dimensional accuracy, material quality, and long-term durability in the demanding marine environment. Salt spray, constant vibration, wide temperature swings, and moisture ingress are realities every marine component must survive — and EMP engineers its parts with exactly those conditions in mind.</p><p>The brand&apos;s catalog spans a remarkably wide range of marine engine subsystems. From cooling and fuel delivery to gearcases, propellers, transom components, and steering systems, EMP offers solutions for outboard engines from manufacturers including Mercury/Mariner, Yamaha, BRP (Johnson/Evinrude), and Force, as well as inboard/sterndrive platforms such as MerCruiser, OMC, and Volvo Penta.</p><h3>Ignition and Electrical Components</h3><p>One of EMP&apos;s most comprehensive product areas is marine ignition and electrical systems. Their <a href="/13199-engineered-marine-products-ignition-control-module-10488">Ignition Control Modules</a> and related ignition components cover a broad spectrum of inboard and outboard applications — from distributor caps and rotors for Volvo Penta V8 engines to ignition coil assemblies compatible with MerCruiser 3.0L through 8.4L GM-based powerplants and OMC configurations. Reliable spark delivery is critical to engine performance and starting consistency on the water, and EMP&apos;s ignition lineup is designed to deliver dependable output across the entire RPM range.</p><h3>Gaskets, Seals, and Engine Integrity</h3><p>Keeping a marine engine leak-free is just as important as keeping it firing correctly.

Product Details

The Engineered Marine Products 47-13142 is a replacement water pump impeller designed specifically for OMC (Outboard Marine Corporation) outboard motors ranging from 25 to 40 horsepower. This critical cooling system component circulates water through the engine block to prevent overheating and ensure reliable performance on the water.

Key Features:

  • Direct replacement for OMC outboard motors 25-40HP
  • Precision-molded flexible rubber construction for optimal water flow
  • Durable nitrile rubber compound resists saltwater corrosion and degradation
  • Factory-spec dimensions ensure proper fit and sealing
  • Essential maintenance component for cooling system integrity

Regular impeller replacement is critical preventive maintenance for outboard motors. Marine technicians recommend inspecting impellers annually and replacing them every 2-3 years or sooner if signs of wear, cracking, or missing vanes are observed. A failed impeller can lead to engine overheating and catastrophic damage.

Application Note: Verify your specific OMC model number and year to ensure proper fitment. This impeller replaces common OMC part numbers for Johnson and Evinrude outboards in the 25-40HP range.

Easy setup

great site

easy and quick!

Quick and easy

I was able to pay with Amazon pay. Excellent choice! This was on a Hummer H2. I replaced all of the 12v adapter rings. They all slide on to place exactly like the broken stock ones. I also like the chrome trim ring for it. I would have liked to have found ones that had the spring associated with the flip up cover, but these do not have the spring. I know they make them, I just couldn't find anywhere that sold them.
